How Tip Calculator Works
Figuring out a fair tip and splitting a bill fairly both come down to simple percentage math applied to the same bill total. The tip calculator multiplies your bill by the tip percentage to get the tip amount, adds that to the bill for the total, and then divides everything evenly across the number of people if you’re splitting.
Formula: Tip = Bill × (Tip % ÷ 100); Total = Bill + Tip; Per-Person Total = Total ÷ People
- Bill — the bill amount before tip
- Tip % — the tip percentage, chosen from the 15/18/20/25% presets or entered as a custom value
- People — the number of people splitting the bill, defaulting to 1

Tip Calculator FAQ
What’s a standard tip percentage at a restaurant?
Most US restaurant tipping falls in the 15% to 20% range for typical table service, with 20% or more common for exceptional service. The calculator includes 15%, 18%, 20%, and 25% presets, or you can enter any custom percentage that fits your situation.Should I tip on the pre-tax or post-tax bill amount?
Tipping etiquette varies, but many guides suggest tipping on the pre-tax subtotal since sales tax isn’t service the server provided. This calculator applies the tip percentage to whatever bill amount you enter, so enter the pre-tax subtotal if you prefer that method.How does splitting the bill between people affect each person’s tip?
The total tip is divided evenly by the number of people entered, regardless of what each person individually ordered. For bills where people ordered very different amounts, you may want to calculate each person’s share of the bill separately before applying the tip percentage.Why is my per-person total not a round number?
Splitting a bill and tip evenly across several people often produces a total with cents, since the math rarely divides cleanly. Round up to the nearest dollar per person if you want a tidier amount, or adjust who pays the extra cents.Is 18% or 20% considered a better tip for good service?
Both are within the commonly accepted range for good service in the US; 20% is generally viewed as more generous. The right choice depends on your budget, local norms, and how the service was — this calculator just does the math once you decide.Does the tip calculator account for large groups automatically added gratuity?
No — some restaurants add an automatic gratuity (often 18-20%) for large parties directly to the bill. Check your receipt before adding an additional tip on top, since the calculator doesn’t detect or subtract an existing service charge.Related Calculators
